Made from ethylene, Mitsubishi Chemical's ethanol is a synthetic alcohol having 95% and 99% anhydrous grades. It is high purity with very low impurity content other than water, and is therefore suitable for medical and cosmetic applications. Other representative uses are as an industrial raw material for detergents, paints, solvents, etc. CAS: No.64－17－5 EINECS: No.200－578－6 Japan, Chemical Substances Control Law: METI-No. 2-202 Japan, Poisonous and Deleterious Substances Control Law: N/A Japan, Fire Services Law: Hazardous material Class 4 Alcohols.
GBL has a wide range of practical applications because of its low freezing point, high boiling point, and a unique combination of solvent and electrical properties. It has applications as a solvent for special resins, in photography, in batteries, and as an electrolyte. Also a number of derivatives are synthesized from GBL. CAS: No. 96-48-0 (T) EINECS: No. 202-509-5 Japan Chemical Substances Control Law: METI-No. 5-3337 Japan, Industrial Safety and Health Law: No. 5-3337 Japan, Poisonous and Deleterious Substances Control Law: Not applicable.

ZELAS™ is a high-performance olefin-based thermoplastic elastomer in which high rubber content in the polypropylene homopolymer matrix due to a combination of outstanding catalyst and polymerization process technologies. Various grades are available for medical applications such as infusion bags / bottles, tubes, seals, etc; automotive interior and exterior parts; as well as building materials.
LINKLON™ is a silane cross-linking resin (polyolefin) in which after the molding process, silane and water inside the material can be activated to react and form a cross-link. By post-cross-linking, the thermal, chemical, and mechanical properties are greatly improved. It is used for electric wire insulation, water / hot-water supply pipes, floor heating pipes, solar cell sealing agent, etc.
Gallium Nitride is one kind of wide-gap compound semiconductors. CAS No.25617-97-4, EINECS Number 247-129-0 Mitsubishi Chemical's Gallium Nitride (GaN) substrate is a high-quality single-crystal substrate. It is made with original HVPE method and wafer processing technology, which has been originally developed for many years. The features are high crystalline, good uniformity, and superior surface quality. GaN substrates are used for many kinds of applications, for white LED and LD(violet, blue and green) Furthermore, development has progressed for power and high frequency electronic device applications. In order to achieve higher quality and productivity, we have been developing the Liquid Phase growth process called SCAAT(SuperCritical Acidic Ammonia Technology) method.
Mitsubishi Chemical's Epitaxial Wafers for Light Emitting Diode are high-quality, high-value-added compound semiconductor substrates. The LED layered structures are epitaxially grown on a Gallium Arsenide or Gallium Phosphide substrate by HVPE( Hydride Vapor Phase Epitaxy) or LPE( Liquid Phase Epitaxy). The features are high intensity and highly uniform luminescent properties. Those substrates are used to make various LED's (infrared, red, yellow, and green).
The strongly acidic cation exchange resins are bead-like products which have a sulfonic acid group in the cross-linked styrene frame. They can be used across the full pH range (0-14), and are relatively stable to temperature, even withstanding high temperatures of 100-120℃. They are used in a wide variety of fields including water purification, water softening, wastewater treatment, purification of pharmaceuticals and food, and catalysis.
The weakly acidic cation exchange resins have the carboxylic acid group (-COOH) as the exchange group. There are two kinds --- a methacrylic acid type and an acrylic acid type. The acrylic acid weakly acidic cation exchange resin is used for processing water with high carbonate hardness. The methacrylic acid type is used for purification of antibiotics and amino acids.
An amino functional group is incorporated into the anion exchange resin enabling the exchange of anions like the Cl- ion and the SO4-- ion. Strongly basic anion exchange resins and weakly basic anion exchange resins can be defined according to the basic strength of the amino functional group. The ion exchange resin that has a quaternary ammonium group is strongly alkaline and dissociates just like NaOH and KOH. Therefore it is called a strongly basic anion exchange resin.
The weakly basic anion exchange resins use either a polystyrene or polyacrylic ester frame and a primary-ternary amino group as the functional group. Although the anion of a salt like NaCl or Na2SO4 cannot be exchanged, the exchange of an anion of a mineral acid such as HCl and H2SO4, or the salt of a weak base like NH44Cl can be carried out.
The low-odor, low-leachable anion exchange resin reduces the release of total organic carbon (TOC) and amines to prevent offensive odors.
Mitsubishi Chemical provides two types of anode materials for lithium-ion batteries: MPG, natural graphite-based materials and ICG, artificial graphite-based materials. MPG shows excellent performance under rapid charging and discharging cycles. ICG has large capacity with improved battery life.
Sol-Rite™, formulated electrolytes in organic solvents, are mainly used for lithium-ion batteries. It is also used for primary lithium batteries and aluminum electrolytic capacitors. Functional additives in the formulation improve battery performance significantly. Sol-Rite™ is the trademark of Mitsubishi Chemical Corporation.
Mitsubishi™ Coke is a raw material used in blast furnaces. The coke is manufactured by blending many types of coal and carbonized (coking) at a high temperature of about 1200 ℃ in a coke oven. Coke is one of the essential raw materials for iron-making in blast furnaces, and is supplied to major steel mills in Japan and other countries.
